The part 29 is of less width than the part 30. The part 3! graduallydecreases in width from its point of jointure with part 32 to its pointof jointure with part 30. The major portion of the length of part 3! isless than the width of part 30 but greater than the width of part 29.The width of part 32 is less than that of the part 39. The width of part33 is less than that of parts 30, 3! and 32.

Each section is formed lengthwise thereof with an outer cavity 43 ofsemi-circular cross-section which is arranged in a portion of part 30and extends throughout part 3!. The cavity 46 is open at its rear endand closed at its forward end, as at 47. The cavity 46 consists of aportion 48 gradually decreasing in width to the closed end 4'! and aportion 49 of uniform width, of less length than and merging at itsforward end into the rear end of the portion 48. Each section is formedlengthwise thereof with an inner cavity of semi-circular cross-sectionwhich is arranged completely in part 33. The cavity 50 is open at itsrear end and partly closed at its forward end, as at 5!. The cavity 5!!consists of a portion 52 gradually decreasing in width to the closed end5! and a portion 53 of uniform width, of less length than and merging atits forward end into the rear end of the portion-52. The cavity 53 is ofless length than the part 33 and has its rear end flush with the rearend of part 33. The wall part of the-portion 490i the cavity 46 isformed with asemi circular groove 54. The wall part of the uniformportion 53 of the cavity each consists of an outer end branch 6! aninner end branch 62, an outer intermediate branch 63, a rearintermediate branch 34, and an inner intermediate branch 65. g The rearend of the branch 6! rnerges into the outer end of the branch 63. Therear end of the latter is closed. The rear end ofthe branch 64 isclosed. The branch 65 establishes communication between the forward endof the branch 54and the branch 63 intermediate the ends of the latter.The branch 62 opens into the cavity 46 and establishes communicationbetween the cavity intermediate its ends and between the branch 54intermediate the ends of'the latter. The branch 5! at its forward endopens into the part 29. The branches 6!, 63 and a portion of the branch64 are arranged in the part 30. The remaining portion of the branch 64is arranged in the part 3!. The branch 62 is arranged in the parts 30and 3!.

The branch55 extends forwardly of the cavity 53 and merges into a rectangularrecess 66 formed in the forward end of the part 33. The passages incrosssection are of curved contour. The closed ends of the branches 65of the grooves 59, 60 extend rearwardly with respect to the branches 66of the said grooves.

The part 38 of each section is formed centrally with a socket 67. Thepart 3! of each section in proximity to its rear end is formed with apair of spaced aligning sockets B8, 69. The part 32 of each section inproximity to its rear end is formed with a pair of diametrically opposedlugs on its inner face.

The sections 2! and 22 are secured together in abutting relation byholdfast elements 7! of a form capable of engaging in the sections whensaid elements are in holdfast position. When the sections 2! and 22 arearranged in abutting relation, the mouth of the socket 67 of section 2!registers with the mouth of the socket 67 of section 22, the mouth ofthe socket 68 of section 2! registers with the mouth of the socket 6B ofsection 22, and the mouth of the socket 69 of section 2! registers withthe mouth of the socket 69 of section 22. A holdfast element I! ismounted in each pair of aligning sockets, by way of example, asillustrated in Figure 2 for securing the sections in abutting relation.When the sections 2!, 22 are secured together, the ribs 25, 25 engage inthe grooves 23, 24 respectively; the grooves 51 of the sections 2!, 22register to form an outer tortuous tubular passage '!2 for fluiddischarge andfor combined air intake and fluid discharge. The passage'!2 opens atits forward end into an outlet ?3 provided by the'innerfaces of the parts 29 of the sections when said sections are in abuttingrelation. When the sections 2!, 22 are secured together, the grooves 58of the sections 2!, 22 register to form an outer tortuous tubularpassage 14 for fluid discharge and for combined air'intake and fluiddischarge. The passage 14 opens at its forward end into the outlet 13.The latter is normally closed by a removable stopper 15. When 75,:

the sections 2!, 22 are secured together, the cavities 49 of saidsections register to provide an outer valve chamber I6 for a globularvalve 1'! and a resilient disc valve I8. When the sections 2|,

- 22 are in abutting relation, the cavities 59 thereof register toprovide an inner valvechamber I9 for a ball valve 89 and a resilientdisc valve 8! When the sections 2!, 22 are secured together, the;grooves 59 thereof register to form a rear tortuousvtubular passage'82for conducting liquid and for conducting combined air and liquid. Whensections 2!, 22 are connected together in abutting relation, the grooves99 thereof register to provide a rear tortuous tubular passage 93 forconducting liquid and for conducting combined air and liquid. When thesections 2!, 22 are secured together in abutting relation, the recesses99 of said sections register to provide a rectangular opening 96 intowhich the passages 82, 83 open. When the sections 2!, 22 are securedtogether in abutting relation, the semi-circular grooves 54 thereofregister at their ends to form an annular forward groove. When thesections 2!, 22 are secured together in abutting relation, the rabbets55 thereof register to form an annular rabbet and the semi-circulargrooves 59 thereof register at their ends to form an annular reargroove. The part 33 of each section is formed with a semi-circulargroove 84 and said grooves 94, when the sections are secured in abuttingrelation, register to form a tubular passage 95 (Figure 2) forestablishing communication between the valve chamber I9 and therectangular opening 59 provided by'the registering of the recesses 96The rear ends of the channels I2, 19 open into the valve chamber T9 atthe opposite sides thereof and intermediate its ends. The rear ends ofthe channels 82, 83 open into the valve chamber I9 at opposite sidesthereof and intermediate its ends.

The attachment includes a forward and a rear combined valve seat andholding member 86, 81, respectively of circular form. The member 86consists of a disc 88 which is mounted in the forward annular grooveprovided by the grooves 54 of the sections. The disc 88 has a centralopening 89 which communicates with the opening 66 Integral with theupper face of the disc 88 is a series of upstanding equi-distant spacedlugs 99 positioned inwardly adjacent the edge of disc 83 and bearingagainst the uniform portions 49 of the cavities 99 formed in thesections 2!, 22. The lugs 99, in connection with the disc 98, form themember 99 of substantially cup-shaped contour. The lugs 99 are spacedoutwardly adjacent to the edge of the wall of opening 89. The valve !9is normally seated on the disc 88 between the lugs 99 and tends tonormally close the opening 89. The valve '5'! is seated on the valve 18and is freely movable within the valve chamber I9. The diameter of thevalve 78 is less than the distance between the lugs 99.

The member 87 consists of a disc 9! formed with an opening 92 whichcommunicates with the interior'of the bottle. The disc 9! is formed witha laterally disposed annular extension 93 which extends into the rearannular groove formed by the grooves 59 of the sections 2! and 22. Thedisc 9! abuts against the rabbets 55 of the sections 2! and 22. Theintermediate portion of the disc 9! is of reduced thickness, as at 94,and upon which normally seats the valve 8!. Formed integral with disc 9!is a series of equi-distant spaced upstanding lugs 95 which abut againstthe uniform portions 53 of the recesses 59 in the sections 2! and 22.The diameter of the valve 8! is less than the distance between the lugs95. The valve 89 seats on the valve 8! and. is freely movable in thevalve chamber I9.

When the sections 2!, 22 are secured together by the holdfast means 1!,the parts 32 of said sections coact to form the attachment with anannular inner end which surrounds and is connected to the portion I4 ofthe neck by the coaction of the lugs I9 with the bayonet-shaped groovesI9. The edge portions 39 of the sections 2!, 22, when the attachment iscoupled to the neck, seat upon the washer or gasket I8. Prior to thecoupling of the attachment to the neck the portion I9 of the neck, aswell as the shoulder I9, is coated with suitable cementitious material93 for the purpose of fixedly and permanently securing the attachment tothe bottle neck. When the sections 2!, 22 are secured together by theholdfast means II, the parts 33 of said sections are brought intoabutting relation and provide an internal inner end part of circularcross-section which extends into and is disposed in concentric relationrelative to the inner face of the neck of the container. The gasket I8acts to seal the forward end of the space formed between the abuttingparts 33 and the inner face of the container neck.

The ball valves are of like construction and each consists of a metalliccover section 97 and a solid metallic core section 98. The latter is ofgreater weight than that of the section 97.

The form shown in Figure 9 will include two like oppositely disposedinterengaging sections (but one of said sections is shown) anddesignated generally at 99. These sections will be similar to thesections 2!, 22, with the exception that the outer grooves which coactto form the air intake and fluid discharge tortuous tubular passageswill be of a different form with respect to the passages 51, 58, andthat the inner grooves which coact to provide the air and fluidconducting tubular passages will be of a different form with respect tothe passages 59, 99. The section 99 corresponds to section 2!. The othersection, not shown, of the form illustrated by Figure 9, will correspondto section 22. The sections of the modification will be of like form,but with this exception, that one section will be provided with a pairof grooves similar to the grooves 23, 29 of section 2! and the othersection thereof will be provided with a pair of ribs similar to the ribs25, 29 of section 22. The description to follow with respect to section99 is to be understood to apply to the section of the modification notshown.

The section 99 includes a pair of oppositely disposed outer grooves I99, I9! of like form and each includes an outer side wall formed of aseries of stretches in angular relation. The said outer wall includes ashort rear end stretch I92 which at its outer end merges into the rearend of an inwardly extending upwardly inclined stretch I93. The lattermerges at its outer end into the rear end of a straight stretch I94 ofmaterially greater length than the stretches I92, I93. The stretch I94merges at its outer end into the rear end of an inwardly extendingupwardly inclined stretch I95 of greater length than stretch I93 and ofless length than stretch I94. The stretch I95 at its outer end mergesinto the inner end of a laterally directed downwardly inclined stretchI95 of slightly less length than stretch I95. The lower end of stretchI96 merges into the rear end of an inwardly extending upwardly inclinedstretch I9! of greater length than stretch I99.

length than stretch I97. The inclination of the latter is less than thatof stretches I93, I05 and I98. The inclination of stretch I96 is lessthan that of stretch I95. The stretches I93, I95, I05. I 91 and I 98 aredisposed at different angular relation with respect tothe lengthwisemedian of section 99. The stretches I92, I93 are disposed parallel tothe longitudinal median of section 99. Each outer groove includes a rearend wall I09. Each outer groove also includes an inner side wall formedwith an opening II I) forwardly of wall I99.

Theinner section of the inner side wall consists of a short straightstretch I I2 extended forwardly from wall I99 and opposing in parallelspaced relation and of less length than stretch I 92. The rear and frontwalls of opening IIIl are indicated at II 3, IIG and they are disposedat upward inclinations. The stretch II2 at its outer end merges into theouter end of the wall H3. The outer section of the inner side wallincludes a rear end stretch II 5 which extends inwardly at an upwardinclination and at its rear end merges into the outer end of wall I I I.The stretch II5 at its outer end merges into the inner end of alaterally directed downwardly inclined stretch I I5 which at its outerend merges into the rear end of an inwardly extending upwardly inclinedouter end stretch III. The outer end stretches III of the grooves I99,IIII merge into each other at their outer ends. The combined intake andoutlet of each outer groove is designated H8. The stretch III opposesthe stretch I 98 and a portion of stretch IIlI. The stretch I I6 opposesa portion of stretch I96. The stretch H5 opposes the stretch I05 and apart of stretch I94. The lower portion of the latter, the stretch I93and a part of stretch I92 opposes the opening H9. The stretches I I5, II6 and I II are disposed in different angular relations with respect toeach other, and are also disposed in angular relation to thelongitudinal median of section 99.

The inner grooves of section 99 are of like form, oppositely disposed,and indicated at II 9, I20. Each inner groove is formed in its innerside wall with an opening I2I which communicates with the recess I22.Each inner groove has its outer side wall I23 inclining upwardly fromits rear to its forward end. Each inner groove has its inner side wallformed of a. rear and a front section I29, I25, respectively, eachinclining inwardly from its rear to its forward end. The rear end of section I29 merges into the outer end of the front wall I 23 of openingI2I. The forward end of section I25 merges into the outer end of therear wall I 2? of opening I2I. Each inner groove includes a rear endwall I28 which merges into the rear ends of the side wall I23 andsection I25. The wall I23 opposes the sections I23, I25 and intermediateits ends opposes the opening I2 I.

The modification of the invention shown by Figure resides solely in adifferent shape of the outer and inner grooves of each section of theattachment than that as shown in Figure 8. In Figure 10 the section I29of the attachment which may correspond to sections 2I, 22 or 99,but-more particularly in contour to that of section 2I or 22,

has the outer grooves formed therein, indicatedindicated at I33, I34.The inner grooves of section I28 are of the same form as the innergrooves shown in Figure 9.

The outer grooves I3I I32 are of like form and are oppositely disposed.Each of the outer grooves in section I28 includes an outer side wallwhich is formed of a rear end stretch I 35 which is disposed at aninward inclination from its rear to its outer end, a laterally directedstretch I33 inclining downwardly from its inner to its outer end, ashort vertical stretch I31, a horizontally disposed stretch I38, avertically disposed stretch I39 and an inwardly extending forwardlyinclined forward end stretch I49. The forward end of stretch I35 mergesinto the upper end of stretch I 35. The lower end of the latter mergesinto the forward end of stretch I 3?. The rear end of stretch I31 mergesinto the inner end of stretch I38. The outer end of stretch I33 mergesinto the rear end of stretch I39. The forward end of stretch I39 mergesinto the rear end of stretch I it. The stretches I31, I39 are disposedparallel to the lengthwise median of section I28. The stretch I38 isdisposed at right angles to stretches I31, I 39 and at right angles tothe longitudinal median of section I28. stretches I36, I31, I38. Thestretch I39 is of greater length than stretch I38. The stretch I49 is ofgreater length than the other stretches, with the exception of stretchI35. The stretch I36 is of materially less length than one of the otherstretches. The stretch I 48 at its forward end merges into the inner endof the wall of the combined. air intake and fluid outlet MI. Thestretches I35, I36 and I99 are disposed in angular relation with respectto the other stretches and in angular relation with respect tothe'longitudi nal median of section I28.

The inner side wall of said grooves I3I, I32 is formed intermediate itsends with an opening I42 which communicates with the recess I 43. Theopening I 42 has a forward wall I44 and a rear wall I45. The walls I94,I45 are horizontally disposed. The opening I45 forms the said inner sidewall into an inner and an outer section. The inner section consists of astretch I46 opposing and disposed at the same inclination as the stretchI35. The stretch I46 at its forward end merges into the outer end of thewall I 45. The outer section of the inner side walls consists of a rearstretch I III opposing a portion of, disposed at the same inclination asthe stretch I35 and terminating at its rear end into the outer end ofthe Wall I94, a horizontally disposed stretch I48, a rearwardlydownwardly inclined stretch I49, a vertical stretch I50, a horizontalstretch I5I, a vertical stretch I52, and an inwardly extending forwardlyinclined stretch I53. The forward end of stretch I 4'! merges into theinner end of stretch I 19. The outer end of stretch I48 merges into theupper end of stretch I99. The lower end of stretch I 49 merges into theupper end of stretch I59. merges into the inner end of stretch I5! Theouter end of stretchgISI merges into the lower end of stretch I52. Theupper end of stretch I 52 merges, into the rear end of stretch I53. Thelatter opposes stretch I99. The stretch I52 opposes stretch I39. Thestretches I49 and I5I overhang stretches I39, I35. The stretch I59,opposes stretch MI; The stretch I98 aligns with the inner end wall I53of the passage. The wall I54 connects the rear end of the stretches I35,I 66 together.

The lower end of stretch I59 The stretch Hi9 overhangs the The stretchesI45, I41, I99 and I53,are

longitudinal median of section I28. The stretch I52 is disposed parallelto and the stretches I48, I5I, as well as the wall I54, are disposed atright angles to the longitudinal median of section I28. The innergrooves I33, I34 of section I28 are of the same form and arrangement asthat of the grooves H9, I20 of section 99.

With reference to the form illustrated by Fig. ure 9, the grooves I00,IUI of one section thereof are adapted to register the grooves I00, I05of the other section thereof to provide oppositely disposedtortuousindependenttubularpassages functioning in the same manner as thepassages 12, 14. The grooves H9, I20 of the sections of the form shownin Figure 9, are adapted to register to form inner tortuous independenttubular passages functioning in the same manner as the passages 82, 83.With reference to Figure 10, the grooves I29, I39 of the sectionsthereof are adapted to register to form a pair of independent tortuoustubular passages functioning in the same manner as the passages 72, I4.Further with ref erence to Figure 10, the grooves I33, I3'3 of thesections thereof are adapted to register to form independent tortuoustubular passages functioning in the same manner as the passages 82, 83.

If the bottle is tilted with respect to the horizontal to the right, thepassage I2 constitutes a fluid discharge passage and the passage 16pro-- vides a combined fluid discharge and air intake passage. If theattachment is tilted with respect to the horizontal to the left, thenthe passage 14 forms a fluid discharge passage and the passage 12provides a combined fluid discharge and air intake passage.

The parts of the attachment are so arranged to provide for discharge ofthe contents of the bottle after the attachment is disposed at an anglewith respect to the horizontal and as the attachment, when extendingdownwardly, is moved towards the vertical, the flow decreases andcompletely stops when the attachment assumes an inverted verticalposition. It is thought that the preventing of discharge from thebottle, when the attachment is in an inverted position and verticallydisposed, is due to an air-trap effect within the attachment. Thetubular passages are of like form, oppositely disposed, of tortuous typehaving offset closed branches and so formed as to prevent the passage ofa wire or other implement to hold valve I8 off of its seattosurreptitiously refill the bottle.

The attachment is for employment in connection with any form ofcontainer having a neck or an annular extended intake or filling member.The term container is also meant to imply a bottle or a jug. The termneck is also meant to imply an annular extended intake or fillingmember.
